What will be managed in the solid materials handling facility?
By-product materials managed on-site will include bottom ash, fly ash and gypsum. The materials will be low in moisture content during placement and storage. To facilitate recycling, the ash and gypsum will be managed in separate storage “cells.” Approximately 118 acres will be used for ash handling and 267 acres used for gypsum handling, for a total of 385 acres. Plant Washington can store up to 30 years supply of both ash and gypsum on site. Plant Washington will not have a slurry pond storage system.
